Notes by Gerry Roach

  1. Our Arizona county prom peak climbs
    Gerry Roach’s totals: 19 ascents; 15/15 overall
    Jennifer Roach’s totals: 15 ascents; 15/15 overall
    Gerry and Jennifer’s combined total as of 11/1/13: 34 ascents
    Gerry and Jennifer finished the Arizona County Highpoint list on 4/16/06 and
    finished the Arizona County Prom Peak list on 11/1/13.

  2. There are 21 highpoints on this list,
    of which 15 are county prom peaks, one for each of Arizona’s 15 counties.
    With the exception that Greenlee County has two candidates for its prom peak,
    this county Prom Peak list has one peak for each of Arizona’s 15 counties.
    There are no twofer county prom peaks in Arizona.

  3. While Gila County has two candidates for its highpoint,
    the most prominent peak in Gila County is Pinal Peak, a clean winner.

  4. In Greenlee County, the prominence of Guthrie Peak is only 3 feet less than the prominence of Maple Peak.
    Since the prominence saddle of Maple Peak is interpolated, Guthrie Peak is a soft contender for the
    most prominent peak in Greenlee County, and we list it.

  5. In this list, Rank by Elevation is in the first column, and Rank by Prominence is in the second column.

  6. All maps listed are USGS 7.5 minute quads unless otherwise indicated.
    The map listed shows the highpoint, and its contour interval is 40 feet unless otherwise indicated.

  7. The datum for the Latitude and Longitude is WGS84.
